Where are the ThingWorx Entities like mashups are stored/Saved? Can that be saved in different folder structure?

The usecase is, need to have same name mashup at different folders like can have same name document in different folders. And then should be able to invoke through REST like Thingworx/Mashups/Planning/MyOpenWork and Thingworx/Mashups/Change Management/MyOpenWork

How can this be made possible? Any pointers, links to relevant documentation will help here.

Vijay, Unfortunately you are not going to be able to control where Mashups are stored. All Mashups are accessible via the REST API like so: "localhost/Thingworx/Mashups/MASHUP_NAME" You need to modify the IP address, port, and protocol as necessary to fit your server configuration.
